Silicon Labs unveiled a dual-mode Bluetooth Smart Ready module BT121 that gives embedded developers flexibility to integrate both Bluetooth Smart and Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) wireless technologies while minimizing design time, cost and complexity. BT121 is ideal for applications requiring connectivity to legacy devices that only support Bluetooth BR/EDR, as well the latest applications using Bluetooth Smart such as connected home, health and fitness, wearables and point-of-sale terminals.
BT121 can connect to legacy devices that only support Bluetooth SPP or Apple iAP2 profiles, for example, as well as to devices that support Bluetooth Smart. The module integrates a high-performance Bluetooth radio with an extended range of up to 400 meters, a low-power ARM MCU, and a fully certified Bluetooth Smart Ready protocol stack supported by Silicon Labs’ Bluetooth Smart Ready SDK and easy-to-use BGScript scripting language with a 11 mm x 14 mm surface-mount package, making this one of the smallest Bluetooth Smart Ready modules in the market.
No RF or Bluetooth protocol development expertise is necessary to implement the BT121 module in Bluetooth designs. The module can be used as a peripheral along with an external host MCU, or applications can be embedded into the built-in MCU with the Bluegiga BGScript scripting language, creating a completely standalone design with minimal external components.
“Our new BT121 solution makes it simple and easy to add Bluetooth Smart and BR/EDR connectivity to wireless designs,” said Riku Mettälä, general manager of wireless module products at Silicon Labs. “Bluetooth Smart is quickly becoming the most widely adopted wireless protocol for power-sensitive personal-area networking applications. Leveraging Bluegiga’s deep wireless expertise, we continue to execute on our roadmap by introducing new Bluetooth modules and software stacks, enabling our customers to respond quickly to the largest, fastest-growing low-power wireless connectivity opportunity in the IoT.”
Pre-production samples of the Bluetooth Smart Ready BT121 module, along with the development kit, are available now for engineering evaluation and prototyping. Volume quantities of the module are planned for Q3.
